Red vs. Blue (2003) : 7x5

After Washington hangs up on Caboose, Donut offers to help him with his project and mentions that the Red team's underground holo-room could be useful before returning to Red base. After another accidental fire, Caboose decides to take Donut's advice and sneaks off toward Red base with Epsilon, planning to check out the holo-room. There, the Reds are making plans to rescue Donut, who returns and explains his brief visit to Sarge. Only Grif notices Caboose's attempt to stealthily enter Red base, but he ignores him and Caboose gains entry to the holo-chamber. Once inside, Epsilon begins to make humming sounds, which alarms Caboose. The scene fades to black and the chapter ends with Caboose mysteriously exclaiming, "It's you."
